Description

@AntonAndreevichMorozAntonAndreevichMorozopened on May 8, 2021

There is such a product WtWare (OS for thin clients). They have a built-in VNC server. I use the new Local Devices feature and noVNC to connect. But I get an error on the current client side. Having tried the same thing in Guacamole, the connection was successful for me. I started looking for information by mistake and sorting out. Found a similar problem with noVNC (https://wtware.ru/forum/viewtopic.php?t=21514 unfortunately only in Russian). It indicates the need to have support for ZRLE encoding in VNC. Then I found discussions about noVNC and this type of encoding. Which brought me to github noVNC novnc/noVNC#545 and see that this issue has been resolved. I tried to compare what might be the differences between the original noVNC and what is built into MeshCentral. Found missing noVNC/core/deflator.js file. Unfortunately my knowledge is not enough to try to implement it.

I will give the connection logs through MeshCentral

Here we see differences only in encoding options. @Ylianst Could you check this issue?
